Pump maintenance for mining and steel
No sector punishes pumps like mining: abrasive slurry devours impellers, liners and seals in cycles measured in months. In steelmaking, descaling water and furnace cooling cannot stop. Hydro Pumps serves both with the same approach: component restoration with materials and coatings superior to the originals.
Where pumps suffer at the mine and the steel mill
Abrasion, solids and continuous operation — the applications that define wear in the sector.
Slurry and tailings pumping
Slurry pumps with accelerated wear of impellers and liners — the mine's biggest consumer of spare parts.
Mine dewatering
High-pressure multistage pumps keeping the pit dry — a dewatering stop is a production stop.
Process and beneficiation water
Flotation, grinding and classification circuits — high flows with suspended solids.
Descaling in steelmaking
Ultra-high-pressure pumps for scale removal — severe demand pulses and mandatory reliability.
Furnace and rolling mill cooling
Cooling circuits whose failure compromises equipment worth far more than the pumps.
Intake and recirculation
Large-flow vertical pumps at tailings dams and water recirculation circuits.
Against abrasion, the right material — not endless replacement
Restoration with coatings that outlast the original
In abrasive service, restoring with the original material means accepting the same wear cycle. Our workshop applies HVOF thermal spray and high-hardness coatings to impellers, casings and sleeves — combinations that extend component life beyond the catalog part.
Every job ships with dimensions restored to design clearances and G2.5 dynamic balancing — because a worn slurry impeller is also an unbalanced impeller, and vibration accelerates the end of bearings and seals.
Maintenance that respects the operation's rhythm
Mining and steel run 24/7 — maintenance must fit short planned stops or happen with the plant running. We work with early inspection, pre-positioned parts kits and field crews for disassembly and assembly within the window.
For the unexpected — a dewatering pump down, a compromised cooling circuit — our 24/7 field service reaches the mine or the mill in any region of the country.

Questions from mine and mill operators
Is it worth restoring a slurry pump impeller, or better to buy new?
It depends on the wear stage and part availability. Restoration with a high-hardness coating typically costs a fraction of a new impeller and, with the right material, outlasts the original in abrasive service. When the geometry is beyond repair, we manufacture to drawing — including via reverse engineering.
Do you service high-pressure descaling pumps?
Yes — high-pressure multistage pumps are part of our scope: impeller and diffuser restoration, clearance restoration, sealing suited to the service and bench performance testing before return.
How does maintenance work without stopping production?
With planning: prior inspection defines the scope, parts arrive before the window and the field crew swaps the rotating assembly or the complete pump within the planned stop. The removed equipment goes to the workshop for restoration and returns as a spare.
Which mining pump brands do you work with?
We are independent and multi-brand: we service KSB, Sulzer, Imbil, Warman and other manufacturers present in Brazilian mining, with compatible spare parts, component restoration and reverse engineering for discontinued items.
